OSCILLATING- CYLINDER. i i i Application filed January 14, 1922. Serial No. 529,211.

To all whom it mag/concern Be it known that I, WILLIAM R. Heron- KISS, a citizen of the United States, and resident of St. Paul, in the countyof Ramsey and State of Minnesota, have invented certain new and useful Improvements in Oscillating Cylinders, ofwhich the following is a specification.

This invention relates to paper straightening devices especially adapted for straightening sheets of paper upon being provide a paper jo ging means which is" slmple to operate, 0 highly simplified con- ,st-ruction and cheap to manufacture.

Other objectsand' advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part'of this application and in which like numerals are employed. to-designate like parts throughout the same,

Figure 1 is a perspective illustrating the improved ogging means inuse.

Figure 2 is a vertical sectional view through a delivery table illustrating the improved jogging means. I

. Figure 3 1s a detail sectional view through the improved jogging mechanism.

Figure 4; is a perspective of a supporting member embodied in the invention.

Figure5 is a plan view of the jogging 7 member or body, the view illustrating the several positions assumed by the same.

.In the drawing wherein for the purpose of illustration is shownthe; preferred embodiment' of the invention the; numeral 5 designates a delivery table arranged at the discharge end of a paper perforating, ruling,-scor1ng, bronzlng or other machine, or at thedischarge end of a printing press. The i paper receiving table 5 is inclined downwardly from the discharge end of the machine, so that as the sheets 6 are discharged, they will move downwardly over the, pile, andcontact with atransverse stop element 7 secured to the table by means of a fastening device 8 associated with a bracket 9.

As illustrated in Figure 1 the delivery table is also provided with a longitudinally extending guide 10 adjustably secured to the table 5 by means of a thumb nut 11 threaded on a screw 12 .passedthrough the bracket. 13. The bracket is permanently secured to the longitudinally extending guide 10 and is provided with a slot for the receptionof the screw 12 so that by loosening the thumb nut 11 the guides may be conveniently adjusted on the table to conform to different widths of paper.

The invention forming the subject matter of this application resides in providingi means whereby the individual-sheets may be properly positioned on the pile upon being discharged from above. In carrying out the invention I provide a joggingbody 15 of cylindrical formation and mount the said jogging body. upon the table so that when the same is operated, the individual sheet will be moved laterally into engagement with. the longitudinally extending guide. With reference'to Figure 2 'will' be seen that an operating shaft 16 is extended upward-1y through the deliverytable 5 and is extended into a socket extending longitudinally in the body 15 andarranged. at a point spaced from the longitudinal ,cen-

ter ofthe same. A suitable pin 17 iseX- tendedthrough the body 15 and the shaft" 16 and, forms, a means to connectthe body 15 to the shaft 16. By thus mountingth e body 15 on the shaft16 the bodymoves lat erally when rotated so as to engage the extended portion of. the sheet and thereby move the same laterally to assume itsproper position on the pile.

The operating shaft 16 is extended through the upper andlower sides 19 and 20 respectively of a 'U-shaped supporting member generally designated by the numeral 21. The U-shaped supportingumember2l which may be formed of any suitable materialis secured to the under side of the table bymeans of-fastening devices 22 and the upper arm 19 is provided with an upwardly extending bearing 24;;th'roaigh which the shaft 16 extends; Thelowerfarm 20fwhich' is arranged in spaced parallel relation to the upper arm 19 is provided with avsocket 25 for the reception of the lower portionof the shaft 16. A suitable weal" are ranged in the lower portion of the socket and reduces the wear on thelparts to a minimum. "When the wear plate 27 becomes worn, a new one may be readily inserted into the socket.

A suitable pulley 29 is mounted on the shaft and is provided with a hub 30 securely connected to the shaft by means of a set screw 31. As illustrated in Figure 1 a belt 33orpther operating means is trained about the pulley '29 and forms a means for operating the shaft and the jogging body.

In opera tion ithe belt 33 is connected to a suitablepart of the machine and operates the pulley .29 so as to force the cylinder to operate. As indicated by the arrow in Fig- ,urel the side of 'the cylinder 15 adjacent the paper moves in the same direction of'tr avel as the paper sodas to urge the paper .the direction of the transverse stop element or Wall 7. In carrying out the invention the ,Cylinder is of aluminum or other light material so as to reduce vibration to adminimum.

A jogger constructed inaccordance with this invention may be conveniently applied to any deliverytable and in use forms a reliable means for properly positioning the indiyidual sheets npon being discharged from the machine. iQwing tothe simplicity of the invention it is not easily broken or rendered inoperative and requires but a small amount of attention on the part of the operator; The improyed jogging mechanism correctly piles the sheets so that the pile may be conveniently removed at the proper time. i

Having thus described the invention what I claim is 1 A paper jogging machine comprising an eccentrically mounted body of elongated formation, and means to revolve the body constantly in one direction whereby the bodymoves laterally and properly positions the sheets forming a pile. I The combination with a deliyei'y table having gnidi'ng means, of an ec centrically mounted body arranged on said table and adapted for engaging the indiyidual sheets ,of apile and moving the same laterally whereby to straighten the sheets, and means to operate said'body, said body having a mqe h's riac 3. combination with an inclined delivery of longitudinal and transverse gnides nio inted thereon, an eccentrically mounted body arran'ge d' on said table topposite said longitudinal guide and adapted for moving the individual sheets into engagement with said longitudinal and said 'lt'ra ns yerse guide, and means to operate said ,0 l ly mounted body whereby to move "thsaime t ra ly whe -owed, s i b y being" of cylindrical formationend having a smooth surface.

4. A jogging mechanism for a delivery table comprising a shaft, a cylindrical body eccentri'cally connected to said shaft whereby the body moves laterally when .the shaft rotates, and means to rotate said shaft, the contact surface of said cylindrical body being unbroken.

A jogging mechanism for a delivery table comprising ashaft, a cylindrical body eccentrically connected to said shaft whereby the body moves laterally when the shaft rotates, means to rotatesaid shaft, and a U-shaped support having spaced armsrotatably connected to said shaft.
